,Explain how carnosine is synthesized a. carnosine (beta-alanyl histidine) is made in the
within the body. body from histidine and beta-alanine via an energy
dependent reaction catalyzed by carnosine
synthetase
b.Found in skeletal muscle, cardiac muscle, brain,
kidney, and stomach.
c. Available in meats and absorbed in intestine via
peptide transporters
d. Antioxidant activity, (hydroxyl and superoxide
radical) and oppose
glycation.
e. Suppress lipid peroxidation and react with
protein carbonyl
f. Regulates intracellular calcium and contractility in
muscle
g. Primarily, carnosine with pH buffering capacity is
widely used in the field of
sports nutrition. Because the dissociation exponent
(pKa) of carnosine is 6.83, it is suggested that
carnosine attenuates the reduction in blood pH by
a large amount of H+ originating from the
dissociation of lactic acid during strenuous
exercise, and suppresses a loss of force
,What is a waxy maize starch and a. A highly branched starch called amylopectin.
what effect does it have on blood Water soluble and absorbed by the gut more
glucose? quickly than dextrose or maltodextrin, research has
not substantiated this claim.
b. Has been shown to be absorbed with less
insulin, allowing ketogenic affects to remain,
increase both glycogen and FFA substrate
utilization.
Based on recent studies, which Vitamin D
vitamin shows evidence of positively
affecting muscle function?

in humans? Give examples of glycerol (a catabolic produce of triaglycerols) and
gluconeogenic certain amino acids (glutamine and alanine)
precursors.
What effect does long-term coffee Results suggest that moderate consumption of

Diabetes? lower risk of type 2 diabetes in younger and
middle-aged women. Coffee constituents other
than caffeine may affect the development of type 2
diabetes.
What effect does supplementing a. The major finding of this investigation was that
with WPI have on muscle damage? whey protein isolate
supplementation attenuated the impairment in
isometric and isokinetic
muscle forces during recovery from exercise-
induced muscle injury.
b. The current study demonstrates that whey
protein in a partially hydrolysed
(pre-digested) form improves strength recovery
rates, possibly due to an increase in the rate of
repair processes and/or a reduction in the extent of
damage, from intense training, in particular,
eccentric exercise that is commonly used in weight
training.
When glycogen stores are depleted, Fat (oxidation)
what macronutrient becomes the
predominant fuel source during
distance running?
